NPC Ukrenergo held the online public hearing of the draft Transmission System Development Plan for 2021—2030.
The preliminary Transmission System Development Plan for 2020—2029 was approved by the Regulator on 3 April 2020.
A key novelty of the new draft is the list of potential power infrastructure objects (Ukrenergo substations) to which new high-manoeuvre generation facilities and energy storage systems can be connected.
“The draft plan we have presented takes into account outcomes of the Generation Adequacy Report and answers the question about the optimum location for construction and connection of high-manoeuvre generation facilities for further operation as part of the IPS of Ukraine. We have proposed the specific markers for future users in terms of the physics of connection and location of these facilities to provide the best system effect for the power system balancing, to reduce electricity process losses in the grid, and to ensure the reliability of power supply to consumers,” said Oleksii Brecht, Director for Grid Operation and Development at NPC Ukrenergo.
Presentation is available here (only in Ukrainian).
As stated in the document, the minimum installed capacity of each new high-manoeuvre generation facility should be from 20 MW to 250 MW. The construction tender for such generation should be conducted by the state, the relevant procedure was approved by the Cabinet of Ministers Resolution No. 677 dated 10 July 2019.
The energy storage and high-manoeuvre generation facilities are called for by the rapid development of generation by the renewable energy sources (RES) in the Integrated Power System (IPS) of Ukraine, primarily by the wind and solar power plants (WPPs and SPPs). They will make it possible to increase the flexibility of the power system that has to intake large volumes of WEPs and SPPs which are difficult to forecast. Over the next 10 years, Ukraine should build 2 GW of new manoeuvre facilities with quick start and 2 GW of the energy storage.
By creating a sufficient volume of the energy storage in the Integrated Power System (IPS) of Ukraine we will also be able to fulfil some of the requirements of ensuring the necessary volume of primary frequency control in the integration process to ENTSO-E. According to Ukrenergo’s preliminary assessments, already in 2021 the IPS of Ukraine can haveabout 200 MW of this reserve.
The draft Plan in the list of investment projects also includes Ukrenergo’s project of creating the energy storage control system of 200 MW capacity. Its implementation is planned for 2020-2021 and its cost is 3.7 billion UAH to be raised as loan proceeds from the European Bank for Reconstruction and Development.
The project of creating the first in Ukraine energy storages launched in 2019 as part of Ukrenergo cooperation with the subsidiary of the French Transmission System Operator Réseau de Transport d’Électricité — RTE International. Today, the project feasibility study is already available and defines the preliminary cost of construction, creates the model of the future storage system, and the road map with the list of all necessary measures to implement the joint project.
In general, the draft Transmission System Development Plan for 2021—2030 envisages raising 66 billion UAH of investments in the period of 2021—2030. Key actions include:
- reconstruction of all operating substations involving the replacement of morally and physically obsolete equipment and the installation of automated process control systems;
- construction of 7 new substations and increase of the transformer capacity to 12,451 MVA. At the same time, in May 2020 the construction of SS 500 kV Kreminska was completed in accordance with the current transmission system development plan, which allowed ensuring the reliable power supply to the north of Luhansk region.
- reconstruction of over 1.5 thousand km of 220—330 kV lines and new construction of about 3 thousand km of 220—750 kV lines;
The implementation of the Development Plan increases the security and reliability of the power supply, responsiveness of the transmission system to the needs of the electricity market, connection to the European network ENTSO-E, and safe integration of renewable energy sources (RES) to the IPS of Ukraine.
The 10-Year Development Plan is developed by the transmission system operator on the annual basis in pursuance of Article 37 of the Law of Ukraine “On Electricity Market” on the basis of the approved Generation Adequacy Report and in compliance with the Transmission System Code. The draft Development Plan is published on NPC Ukrenergo’s official website.
